Effect of Different Parameters on Heat Generation and Tensile Strength of FSW AA5083 Joint

Friction stir welding (FSW) is an advanced and upgraded version of friction welding. It has been systematically developed for joining non-weldable aluminium alloys. This joining process is a more robust process for aluminium. In the joining of Aluminium base alloys with friction stir welding, different parameters― tool rotational speed, tool tilt angle ― influence the quality of the weld. In the present article these effects have been identified through one factor at a time approach. Tool rotational speed has been the major influencing parameter for generating frictional heat. Tool rotational speed with frictional heat makes the material to reach at re-crystallization temperature at which two plates were welded. Other parameters also have significant impact on the friction stir welded joint quality. Microstructure also changes at different level of parameters.
